SEAM=PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,417, dated December27, 1887.

Application filed January 24, 1887. Serial No. 225,400. (No model.)

To all whom it may concern:

Be it known that I, HENRY FELLows, of Haverhill, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Seam-Pressing Machines, of which the following is aspecification.

My invention relates to seam-pressing machines of the class employingtwo rollers or wheels so arranged that their peripheries will roll incontact with or close proximity to each other, and in which the pressingof a seam is effected by interposing or feeding the article containingthe seam with the latter in proper position between such rollers orwheels.

My invention consists in the improvements hereinafter described, andsubsequently pointed out in the claims.

I will now proceed to describe my invention, so that others skilled inthe art to which it pertains may make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, forming a part of this specification, in which drawings- Figure1 represents a rear elevation,partially in section, of a seam-pressingmachine embodying my invention. Fig. 2 represents a front elevation ofthe front portion of the machine. Fig. 3 represents a sectional view onthe line 2 2, Fig. 2. Fig. 4 represents a bottom plan view of the upperseam-guide.

The same letters of reference indicate the same parts wherever theyoccur.

(1 indicates the bed of the machine; I), the r ear standard, and c theoverhanging arm, in which is j ournaled the main shaft d, provided onits rear end with the driving-pulley c and on its front end with theupper seam-pressing roller, f.

Suitably journalcd in the rear standard, b, is a vertical shaft, 9,provided on its upper end with a bevel-gear, h, engaging a similar gear,2', on main shaft 11, and having a bevel-gear, j, on its lowerend,engaging a like bevel-gear, k, on a horizontal shaft, Z, adapted toturn in bearings under the bed of the machine.

on indicates a vertical shaft suitably supported and journaled inbearings in front of front standard, 12, said shaft being provided onits lower end with a bevel-gear, 0, intermeshing with another gear, 1),on horizontal shaft Z.

(1 indicates the lower seam'pressing roller, having bearings in theadjustable bar or rod 0 stepped on ayielding cushion,s, to compensatefor varying thicknesses of goods being operated upon, as also otheremergencies.

It will be seen that lower seam-pressing roller, g, has a diametersubstantially twice that of the upper roller, this construction be ingfor the purpose of securing a longer pressingsurface between the tworollers and prevent the crimping or curlingof the work which would belikely to occur if the rollers were small and of the same size. In orderto obtain the same surface speed of the two rollers, the lower one isdriven at a slower rate than the upper, this variation in speed beingsecured by making bevel-gear 0 substantially twice the size ofbevel-gear p.

Affixed to the forward end of the journalshaft. of lower roller, q, is abevel gear-wheel, t, intermeshing with a like gear-wheel, u, splined onshaft m, so that it can move longitudinally thereon,as well as berotated thereby. A small bracket, o, extends outward from the upperforked end of supporting-rod'r and surrounds vertical shaft m, affordinga support for bevelgear a, so as to always keep it in engagement withgear t.

By the means described I am enabled to opcrate both seam-pressingrollers in unison and in a positive manner.

20 represents the lower guide, which is adapted to support and assist inguiding the work being fed between the seam pressing rollers. Said guideis securely attached to a projection, 00, on the supporting-rod r bymeans of a screw, y, or in any other suitable manner. Another screw orstud, .2, passes through a slot in the lower end of the shank of saidguide and into the frame of the machine, to merely hold said shank frommoving laterally out of place at this point. By this construction itwill be seen that guide 10 is made to always maintain the same relativeposition with respect to lower roller, q,that is, as said roller ismoved vertically by varying thicknesses of work that pass between therollers, guide w moves in unison with it.

a represents the upper guide, provided with a slot, 1), extendingvertically upward into a chamber formed in the end of a bracket, 0,secured to the side of the overhanging arm 0,

ICO

as shown in Fig. 3. An adjusting-stud, d, is screwed into the upper endof stud b, and is arranged to have its head 0 rest upon the upper end ofthe chambered end of bracket 0'. A spiral spring, f, surrounding stud band arranged to bear at its lower end, 9, of said stem, and at its upperend against the bracket 0, serves to keep said guide a presseddownwardly in its normal position, and yet allows it to yieldvertically, in case of emergency, for the passage of any unusually bulkypart of a seam or other unevennesstherein. Adj ustingstud (1 enables theoperator to adj ust guide a vertically in a position best adapted to thegrade of work being operated upon, the yielding connection of saidguide,with its support, being, as has been intimated, to provide forsuch unevenness as may occur in the seams. A guide or steady pin extendsthrough bracket 0 into a slot, d, formed in stud b, in order to maintainguide a in position---that is, from turning on stud b as a pivot.

In Fig. 4 I have shown a bottom plan view of guide a',wherein h ]L2represent two springs, secured by solder or in any other suitable mannerat one end, one to each side of the guide-groove i, the other or freeends of said springs extending rearwardly to a point preferabl yslightly beyond the guide, where they approach and bear against eachother, so that the projecting edges of the seam passing throughguide-groove i,whether said seam be formed on thick or thin stock, itwill be held in proper position by the springs h h as it passesfroni'the guide to the rollers.

j indicates wire or small strip of metal,secured at its forward end onthe upper surface of guide a, and bent around and secured inguide-groove 1' between springs h If, in which position it extends backto a point slightly beyond the rearward ends ofsaid springs,where it isprovided with a plow-shaped enlargement, k, adapted to enter between theprojecting edges of the seam, and so spread them slightly, as to insuretheir proper presentation to and pressing or rubbing by said rollers.

Though I have been particular to describe the form and arrangement ofthe various parts, it is obvious that these may be varied within thelimits of mechanical ingenuity without departing from the nature orspirit of the invention.

Having thus described my invention, what I claim is 1. In a seampressing machine, the positively-operated roller f, roller q, a yieldingsupport, 1', therefor, the horizontal journalshaft of said roller q, agear fixed thereon, a vertical shaft, a gear splined thereon to turntherewith and move longitudinally thereon and intermeshing with thefirstmentioned gear, and gearing for rotating saidseeond shaft,constructed, combined, and arranged substantially as and for thepurposes hereinbefore set forth.

2. In a seampressing machine, rollerf and its support, roller q, and anadjustable and yielding support, 1', for the same, in combination withguide 10, secured to the yielding support for the latter, constructed,arranged, and operating substantially as set forth.

3. An upper roller, f, a lower roller, (1, and its yielding support 1',and means for operating said'rollcrs, in combination with a lower guidesecured to the yielding support 1' of the lower roller, the upperguide,and its support, said upper guide being adjustabl y and yieldinglyconnected with its support, all constructed, arranged, and operatingsubstantially as set forth.

4 The guide a, provided with a guidegroove, in combination with thesprings h h, all arranged, constructed, and operating substantially asand for the purposes set forth.

5. The guide a, provided with a guidegroove, in combination with thesprings h h and the wire or strip of metal j, provided with theplow-shaped enlargement I all constructed, arranged, and operatingsubstantially as and for the purposes hereinbefore set forth.

Intestimony whereol'I have signed my name to this specification, in thepresence oftwo subscribing witnesses, this 17th day of January, A. D.1887.

HENRY FELLOlVS.
